A media transport apparatus and method includes a first media transport having a first drive unit, configured and operative to convey the substrate media through a marking zone to be marked by a print head. A first motion encoder is operatively connected with the first media transport, configured and operative to output a first signal dependent upon the motion of the first media transport surface. A second media transport with a second drive unit and second motion encoder is configured and operative to receive the substrate media from the first media transport and to convey the substrate media. The second drive unit drives the motion of the second media transport with substantially the same surface velocity as the first media transport. The first and second media transports are each operative to hold the substrate media in contact therewith, with respective first and second hold-down forces that may be different magnitudes, including the first hold down force of the first media transport having a greater magnitude than the second hold down force of the second media transport while the substrate media is at least partially within the marking zone and is subjected to both the first and second hold down forces.
